Thesame comprises a pair of similar, symmetrically placecl; vertical coextensive slide or slider members I 6 onwhich is mounted a window ll. One'slider'member l6 slides in each one of the grooves I4 and is of angular transverse cross section, being formed with a rear inwardly extending wall or flange 1 Hand 2. side forwardly extending wall or flange-Ml, thereby forming an angularvertical rabbet or notch ii at the inner front' sicle thereof. At the lower ends ofthe slider members I 6 are rotatably mounted a pair of aligned, symmetrical, horizontal pivot pins-22. Each-slider member I8 is formed with a *h'ole or socket 23 to receive one-end of the pivot pin. Each pivot pin 22 isformed"at anintermediate portion thereof 'witha pair ofmilled fiat-faces 22a forming a web 222) therebetween ofuniform thickness. The pins -22 project inwardly fromthe flanges 20 and project into the rabbets or notches 21. The-window sash ll is pivoted to the slidermembers -l6-by means of said "pivot'pins 22. Said window sash ll comprises a rectangular sash frame 25 having a bottom=portion 26, a top portion 27!, and side portions 28. The sash frame 25' carries the windowpane-tlll. Theside portions 28 'are each fo'rmedat their outer surfaces and adjacent their rear'sur-faceswith vertical grooves 3 I It"will -be=notedthat the side edges of the window sash ll are received within the notches 2| ofthe slider-"members. The notches 3| form vertical chamberswith the slider members for the purposehereinafter appearing. The sash frame"25-is-formed' adjacent the lower end thereof'withsockets 33 to receive the inner ends of" the pins "22*; The pins 22 may be fixed to-the SaSh 'frameZSas'by set screws 25 or :in any othersuitable' manner.

It will be noted that the pins '22"traverse the The height of the, window sash l1 mayjb-thsame .as the height of the slider members. When the window sash is in vertical position-it'maymove upland down together withtheslider members. 7

Means is provided to support the window sash. ll in inclined-fventilating position'or in horizontalfcleaningi position. To this end thereis mounted'oonvea'ch pivoti pin' and within each chamber M, a leverillllzr The levers dlharesimrlar; andrsyrnmetri'cally' disposed 'to .one another so that only one or said-"levers will b ses-embed. Each lever 40 isi'formed adjacentthe lower end thereof 'with an inverted key hole 'shapedslot or opening havinga circularwportion lla and a straight slotted portion 43 extending upwardly from the circular portion.

When the lever is pulled upwardly, said lever may rotate about the pin 22. When the lever is pushed downwardly the web 22b of the pin 22 will be received in the slotted portion 43 so as to prevent rotation of the lever relative to the pin and window. Each lever 46 is formed with a lower portion 44 adjacent the slider member and with an intermediate horizontal offset portion 45 and with an upper portion 46 parallel and offset from portion 44 and located adjacent the inner surface of the sash frame 25.

formed with an outwardly offset finger 4'! which may be engaged or grasped by the fingers of the operator whereby the leverv 48 may be pulled upwardly or pushed downwardly to engage or disengage the same, respectively of the pin55 of the sash frame 25.

, Said lever is furthermore formed adjacent its upper end witha bayonet slot 50. The slot 50 extends from the forward edge of the lever and has an upwardly extending slotted portion 52.

Attached to the outer sides or outer edges and upper corner portions of the sash frame 25 are pins 55 adapted to enter the bayonet slots 50. When the levers 40 are pushed downwardly to engage slot 43 with web 2%, pin 55 will enter the longitudinal portion 52 of slot 50 to lock the window to the lever.

Means is provided to interconnect each lever 48 with its slider member l6. To this end there is pivoted to each slider member as at Gil, a link 6|. The link 6! is interpivoted by pivot'62 to a second link 63. Link 63 is pivoted as at 64 to lever portion 46. The links 6!, 63 areso proportioned as to retain the levers at about 45 inclination. The pivotal point 64 may be somewhat above the offset 45 as shown in the drawing.

. Means is further provided to interconnect the lever 40 to the window ll. To this end there is pivoted to each lever portions 44 as at 66, a link 6?. The link 6! is interpivoted as by pivot 68 to link 69. Link 69 is interpivoted as at H! to the window frame ll. It will be noted that the links BI, 63 are located between lever portions 46 and slider member l6 and disposed within chamber 3 I. a I

It will be further observed that the links 61, B9 are interposed between lever portions 44. and the sash frame 25 and within chamber 31.,

Means is provided to lock the windowsash to the sliders in vertical position. To this end each slider member is formed adjacent the upper end thereof with a horizontal recess or blind opening 86. Received within each recess is a cup 8| formed at its front end with a ball seat 82. Seated on the ball seat 82 is a ball 83. Inter;-

posed between the ball 83 and the bottom of the cup is a coil compression spring to retain the ball 83 on the seat 82. surfaces and upper corner portions of the sash frame are socket members. 85 adapted to receive the portion of the ball which projects from the socket Bl. It will thus be understood that when the window sash is in vertical position, the balls 83 will snap into the sockets 85 to retain the.

window sash in vertical position.

- If it is desired to move the window sash to an inclined position for ventilating purposes, the top of the sash frame 25 need merely be grasped and the window sash pulled inwardly to releasethe balls 33 from the sockets 85. The window sash The lever near the upper end of the window frame, is

Attached to the outer position.

I! together with the levers 40 will then swing about the pivot pins to substantially a 45 angle and will be supported in such position by the links 6!, 63. If it is desired to thereafter move the window sash to a horizontal position as shownin Fig. 4, it is merely necessary to grasp the fingers 4! of the levers 40 and pull the levers upwardly to release the window sash for swinging movement relative to the levers. The window sash can then be moved down to horizontal position and will be supported in such position by the links 6?, 69.

/ The window sash can be moved back to inclined position and the levers 46 are thereafter 'then moved downwardly to engage pins 55 with the slots 51! and also so that the slot portions 43 will engage the webs 22b of the pivot pins 22.

' From inclined position, the window sash can very easily be moved back to vertical position where the balls 83 will. again snap into the sockets 85.

In Fig. 9 there is shown a modified construction which permits adjusting the window to angles other than 45 and horizontal. As shown in Fig. 9, pivoted to the sliders it as at Ma are links em formed with longitudinal slots Glb. Pivoted to the levers 4!) as at 640: are links 62a formed with longitudinal slots 62b. Extending through the crossing slots Bib and 62b is a bolt 620 provided with a wing nut 62d. It will now be understood that the lever 40 may be moved to various angles and the links may be fixed in desired position by means of the wing nut 62d.

It will now be seen that I have provided a construction whereby a pivoted window sash can be tilted inwardly to an acute angle for ventilating purposes, and also providedmeans whereby the window sash can be maintained in such movably connected links. One set being movably attached to a shiftable bar which is releasably attached at its upper and to the upper end of the window sash at one side edge thereof, and the other set being movably attached to a like bar, similarly attached to the opposite edge of the window. Two additional sets of movably connected links are, likewise, attached to the bars and the opposite side edges of the window sash whereby said window sash can be further tilted inwardly beyond the acute angle to a substantially horizontal position when said bars are released from the window. The additional setsv of links support the window sash in a substantially horizontal position, primarily, for cleansing. purposes, since it is self evident that the ven' v tilation would ordinarily be much increased by a It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and Which is well adapted to meet the condtions of practical use.

As various possible embodiments might. be
